Andrew works closely with Sir Nicholas Grimshaw to cultivate relationships with clients and other institutions worldwide while managing the partnership's design approach, public relations and external communications. He has been an instrumental part of Grimshaw since the earliest days of the practice and has been Partner-in-Charge of a diverse range of projects. His award-winning architecture includes the International Terminal at Waterloo Station and the redevelopment of Paddington Station in London, the Experimental Media and Performing Arts and the Eden Project in Cornwall.

During his ten years as Partner-in-Charge of the New York Office, Andrew established Grimshaw as one of the eight architectural practices eligible for major public projects in New York City under former Mayor Michael Bloomberg’s Design Excellence Program. The practice was also cited by the Wall Street Journal as the international architect with the biggest impact on New York over the last ten years

Andrew has guided a series of international exhibitions of the partnership's work. Most recently, the practice presented Elements in Milan, Italy, presenting the work of Grimshaw's Industrial Design Unit. The exhibition revealed three new furniture pieces and chronicled decades of Industrial Design from the Grimshaw studio. In 2013, Andrew co-founded the Urban Research Unit (URU), an initiative conceived by Grimshaw, Future City and the University of the Arts, aimed at developing a fresh approach for intelligent and creative urban placemaking.
